背景 | The retinoblastoma tumor suppressor protein, Rb, regulates cell proliferation by controlling progression through the restriction point within the G1-phase of the cell cycle (1). Rb has three functionally distinct binding domains and interacts with critical regulatory proteins including the E2F family of transcription factors, c-Abl tyrosine kinase and proteins with a conserved LXCXE motif (2-4). Cell cycle-dependent phosphorylation by a CDK inhibits Rb target binding and allows cell cycle progression (5). Rb inactivation and subsequent cell cycle progression likely requires an initial phosphorylation by cyclin D-CDK4/6 followed by cyclin E-CDK2 phosphorylation (6). Specificity of different CDK/cyclin complexes has been observed in vitro (6-8) and cyclin D1 is required for Ser780 phosphorylation in vivo (9).视网膜母细胞瘤肿瘤抑制蛋白Rb通过控制细胞周期的G1期限制点的进程来调控细胞增殖(1)。Rb具有3个功能特异的结合结构域并能够与转录因子家族的关键调节蛋白E2F、c-Abl酪氨酸激酶和具有保守的LXCXE模体蛋白相互作用(2-4)。CDK介导的细胞周期依赖性磷酸化能够抑制Rb靶向结合并允许细胞周期进程(5)。Rb的失活和随后的细胞周期进程似乎需要伴随周期蛋白E-CDK2磷酸化的cyclin D-CDK4/6初始磷酸化(6)。离体已经观察到不同CDK/cyclin复合物的特异性(6-8),而且周期蛋白D1为第780位丝氨酸在体磷酸化所必需(9)。 |

参考图片Western blot analysis of extracts from human fibroblasts synchronized by serum deprivation, using Phospho-Rb (Ser807/811) Antibody. Cells were synchronized for 24 hours then released by addition of serum and harvested at the times indicated. Cell cycle progression was verified by cyclin analysis and FACS.
